In short, Omnatuor.com can be described as a shady website trying to allure users into allowing fake push-notifications. The website is actually a part of huge "darknet" advertising network, that uses social engineering tricks to delude inexperienced users and make them subscribe to unwanted browser notifications. However, as long as the story goes, there is a lot more to point about it. Such websites are usually meant to create adware-based traffic for revenue purposes. This means that by enabling such notifications provided by Omnatuor.com, you expose your desktop to being a receiving end for unwanted content (e.g. ads, banners, coupons, etc.). Even if they seem to be nice at first glance, interacting with such banners may lead to visiting explicit and malicious pages. Also, worth noting that if you stumble upon this redirect each time using your browser, your PC might be in claws of adware infection. This, therefore, can put your data at serious risk because such apps are capable of tracking personal data and selling it further on the dark market. To make sure you are safe from this, we insist on disabling push-notifications and deleting a program that causes redirects to Omnatuor.com. All the necessary instructions to do so can be found in our tutorial below.

Dllhost.exe is a piece of malicious software masking itself under dllhost.exe (COM Surrogate) - a legitimate and important Windows process running by default inside of each system. By doing so, the virus attempts to prevent users from thinking it is something suspicious. It is also possible to see a number of genuine dllhost.exe processes in Task Manager eating tons of CPU resources. For instance, a trojan called Poweliks is known to exploit the legitimate process to execute its dirty work. The malware we are talking about today creates a separate fake process to execute its unwanted tasks. It was found that users affected by it see force-open websites like adult pages, casinos, gambling, phishing, scam, pornography, and other types of resources promoting potentially dangerous content. The list of possible malware functions does not end with forcing redirects only. Such infections may embrace screen/audio recording features, keystroke memorization, spying on sensitive data, installation of malicious programs like crypto miners, and other similar things. If you suspect being infected with Dllhost.exe-masqueraded malware, make sure you follow our tutorial below to detect and remove it immediately.

Kekware is a recent ransomware-type virus. The main symptom of this infection successfully breaching the system is strong encryption of data. As a result, users will no longer be able to access or modify files as they used to do previously. Victims will also see a change in how their data appears - all encrypted samples get renamed according to the following pattern - [random_string].[original_extension][random_string].cyn. To illustrate, a file like 1.pdf may change to something like 7462.jpg7088.cyn and reset its original icon as well. After this part of encryption is done, the virus creates a file called YcynNote.txt, which holds decryption instructions. As said within the note, victims ought to pay a ransom of $500 in bitcoin to the attached cryptocurrency wallet. If victims decide to not follow the demands, cybercriminals say no decryption of data will ever be possible without their involvement. Unfortunately, at the moment of writing this article, this claim should indeed be taken quite seriously. If you do not have backup copies of data saved on external storage devices, you will have a bare chance to decrypt the Kekware data using third-party tools.

NOKOYAWA is a ransomware-classified infection that runs encryption of data and blackmails victims into paying money for its recovery. A report published by Trend Micro featured similar attack traits of NOKOYAWA Ransomware to Hive - a widespread and disruptive group of developers that breached more than 300 organizations in just a few months. Cybercriminals behind NOKOYAWA Ransomware use the .NOKOYAWA extension to rename targetted data. For instance, a file like 1.xlsx will change its name to 1.xlsx.NOKOYAWA and reset the original icon as well. Successful encryption is therefore followed by ransom note creation - the NOKOYAWA_readme.txt file arrives on the desktop. Inside this note, cybercriminals attempt to convince victims into opting for paid decryption. They duplicate information in English and Chinese guiding to contact extortionists through one of their e-mail addresses (brookslambert@protonmail.com or sheppardarmstrong@tutanota.com). Should victims repel their suggestions, the swindlers threaten to publish, as they say, "black shit" to open-access resources. The price for decryption is kept secret until victims establish the contact and it is also likely to be evaluated individually for each victim. In other words, the amount of ransom may range vastly depending on how valuable the captured data is. As a rule, it is not recommended to trust cybercriminals and follow their demands since it can cost you simply a waste of money.

D3adCrypt encrypts system-stored data (with the .d3ad extension) and demands victims to pay a monetary ransom for its return. For instance, a file like 1.pdf will become 1.pdf.d3ad resetting its original icon as well. There is also a ransom note being created (d3ad_Help.txt) explaining to victims how they can return access to files. It is said victims should write an e-mail with their personal ID to the provided d3add@tutanota.com address. In case nobody responds, there is an extra e-mail victim should contact as well (propersolot@gmail.com). Cybercriminals conclude the ransom message with warnings against renaming files, decrypting files on your own, or trying to involve the help of third-party entities. Note that the price for decryption is kept secret until victims establish further communication with cybercriminals. It is also possible for the price to vary depending on how much informational damage victims suffered during encryption. Usually, cyber experts do not recommend paying the ransom - extensive researches show that many extortionists fool their victims and do not provide them with promised decryption tools. Alas, there are no feasible ways to decrypt your data at the moment of writing this article. It may become possible in the future, but no one can say when. You can try some trusted and globally-used tools from our guide below, but there is no guarantee they will be able to actually help. For now, the best way you can avoid paying the ransom and recover your data at the same time - is via backup copies.

Discovered by MalwareHunterTeam, Spark is a ransomware virus designed to keep files at lock and blackmail victims into paying money to return them. This is done through the so-called encryption process when infections of such use strong military-grade algorithms to generate ciphers. As a result, data becomes no longer accessible to users. People attacked by Spark Ransomware will see their files change to something like this 1.pdf.Spark and reset their icons. After rendering all targetted files restricted, the virus displays a pop-up window containing ransom instructions. Cybercriminals say decryption is impossible without a special private key. This is why victims are guided to purchase the key by contacting developers via their e-mail address (notvalidemailadress.ransom@gmail.com). Swindlers also warn against doing modifications to files shutting down the PC, which may result in permanent data loss and system damage as well. There is a timer, within which, victims should contact developers and pay for decryption. However, extortionists do not specify what will happen after the time expires. Based on other ransomware analyses, many frauds threaten the collected data to be permanently deleted or leaked to dark web resources, though, it does not prove this is the case with Spart Ransowmare as well. It is unfortunate to acknowledge, but you are less likely to find a 100% working decryption tool for .Spark files.

Blandcaptcha.top is a deceptive website making bad use of the push-notification feature to promote spam content. On the initial basis, push-notifications are a legitimate feature available in many popular browsers allowing legitimate resources to notify you about new updates right on a desktop in the bottom right corner. Unfortunately, fraudulent marketers exploit this feature to trick inexperienced users into subscribing to unwanted and spammy advertisements. Blandcaptcha.top may ask its visitors to click on the "Allow" button under the pretense of verifying that you are not a robot, watching a video, downloading your file, or something similar. As mentioned, doing what such websites say will lead to unstoppable streams of unwanted banners right on your desktop. The displayed content may supply users with threats about fake system infections, advertise unwanted software, adult websites, and fake lottery winnings. This deceptive marketing technique may target both Mac and Windows users. We thus recommend you follow our guide below if you are victims of Blandcaptcha.top. Instructions underneath will also be suitable for other websites of such in case a similar incident occurs in the future.

Ursearch.net is a fake search engine address, which can be displayed in browsers due to a hijacker infection. Browser hijackers are a type of unwanted software designed to replace default browser settings with fake search engines and suspicious advertising algorithms. Such changes are thereby used to cause unauthorized redirects and generate illegal traffic on entered queries. The main reason why Ursearch.net is considered fake and therefore unable to bring any unique value to users comes from its reliance on legitimate search engines like Google or Yahoo to generate results. Browser hijackers and other similar software like adware may also be able to keep track of sensitive information entered in browsers (e.g. passwords, IP-addresses, geolocations, history, cookies, etc.) and use it for future monetization abuse. It is also worth mentioning that domains like Ursearch.net do not work without support - this is why they are usually backed by extensions or small desktop applications running as a background process in Task Manager. If you are also one of the Ursearch.net victims, follow the guidelines below to remove it and restore your safety.
